 * ```typescript
 * import {
 *   loadFileFromPath,
 *   processFileFromPath,
 *   listSupportedFileTypes,
 *   getCliUsage,

 *
 * // Process a file from the CLI
 * const result = await processFileFromPath("./document.docx", {
 *   verbose: true,

 * });
 *
 * if (result.success) {
 *   console.log(result.output);
 * } else {
 *   console.error(result.error);
 * }
